AUTOMOBILE STORAGE "BATTERY.

Application filed August 11 1925. Serial No. 49,632.

Thisinvention particularly pertains to a device adapted to be applied to the binding posts of storage batteries and has as its primary object the provision of a means whereby sloppa e t acid and passage of fumes through t e seal around the'post will be inhibited.

Another object is to provide a device of the above character which is acid resistant throughout and which is so constructed that it may be readily applied to a battery binding post to effect intimate contact therewith and with the battery cover.

The invention resides enerally in the dprovision of an annulus ormed of lea or other suitable acid-resistant material and in forming the annulus with an inturned margin and a downturned margin to which margins are applied resilient washers composed of rubber composition or other suitable acidresisting material.

The invention is illustrated in panying drawings, in which:--

Fig. 1 is a View in vertical section illustrating the application of the invention to the binding posts of a storage battery and showing the attachment as seen on the line 11 of Fig. 2;

2 is a plan view of the device;

the accom- Ifiig. 3 is a view of the device as seen in side elevation.

Referrin to the drawings more specifically, 4 in icates the top wall or cover of a battery, 5 designates a binding post projecting through the wall 4 and connecting at its lower end with the battery lates 6, and to the upper end of which bin mg post is attached a clamp 7 in the mannercommon in wet storage battery terminal construction such as 1s ordinarily employed in the storage batteries used in they electrical systems of motor vehicles and the like.

8 indicates generally the device embodying the present invention which comprises a rigid annulus 9 formed of lead or other acld-resisting material, which annulusis formed with an inturned marginal lip or flange 10 and with a downturned marginal flange'll. Annular washers 12 and 13 formed of rubber or other suitable resilient material of acid-resisting character are mounted on the flanges 10. and 11 to roject beyond the end faces thereof; the was er 12 being formed with a circumferentiallly extending channel 14 on its outer perip cry to receive the V spaced, thus afl'ordmg around the binding post will flange 10, and the washer 13 being formed on its upper edge with a channel 15 to receive the flange 11. The underside of the washer 13 isdished as indicated at 16 in Fig. 3, to form lips 17 and 18 on the inner and outer lower peripheral edges of the washer.

In the application of the invention the device is placed to encirclethe binding post by inserting the latter through the washer l2 and advancing the device on, the binding post until the washer 13 is brought into contact with the battery top. The washer 12 has an internal diameter slightl less \than that of the binding post whic latter is a close contact between the washer 12 and the binding post.

The inwardly and downwardly pro ecting flanges l0 and 11 with the washers 12 and13 thereon afford a space within the device surrounding the base portion of the binding post,'which space is preferably filled with a heavy grease as indicated at 19 in F ig. 1. The clamp 7 is then engaged with the upper end portion of the binding post and positioned to bear on the washer 12v so as to crowd the Washer 13 tightly against the'battery top.

It will now be seen that b the use of this device the sloppage ofaci or leakage of fumes from the interior of the battery up I be effectively prevented thereby obviating corrosion'of the inding post and clamp, and thus avoiding the difficulties incident to such corrosion. I claim v 1. An attachment for the binding posts of storage batteries, comprising an annulus formed with an inturned marginal flange and a downwardly extending marginal flange, a resilient washer formed with a peripheral channel receiving the inturned marginal flange, said washer being adapted to encircle a binding 0st, and a second resilient washer formed with a top channel to receive the downwardly extendingv flange and arislng from and adapted to seat on the top of the battery.

2. An attachment for the binding posts of storage batteries, comprising an annulus formed with an inturned marginal flange and a downwardly peripheral channel receiving the inturned marginal flange, said washer being adapted to encircle a binding post and contact thereextending marginal flange, a resilient washer formed with a.

with, and a'second resilient washer formed turned flange, washers projecting from the with a top channel to receive the downwardend faces of said flanges; one of which 1y extending flange and adapted to seat on Washers is adapted to encircle and abut the top of the battery, said lastnamed against the binding post and the other '1 i washer being formed with a dished lower washer beIng adapted to seat on the top wall surface. of the battery; said annulus and washers 3. An attachment for storage batteries forming achamber around the binding post;- comprising in combination with a binding and a grease packing within said chamber. post and the battery top wall through which .In testimony whereof I have afiixed my 90 lo the binding post projects, of an annulus have signature.
